Análise comparativa entre o método construtivo utilizando formas de alumínio versus o método convencional em concreto armado.

Abstract

This work presents a comparison between two constructive methods: conventional construction method and concrete walls using aluminum forms. The paper proposes to present, in terms of: cost, labor and productivity discussions and which method is most advantageous. The method consists of a case study comparing two projects, one whose construction was done through the conventional method, and the other was made from the method of concrete walls molded in loco, using aluminum forms. It was observed that the concrete walls method, when using aluminum forms, presents a reduction 6,14% of the total cost of the work, together with a decrease of more than half of the used labor compared to the conventional construction method. In addition, it showed a productivity, more than double, when compared to the conventional construction method. Therefore, although the initial cost of aluminum forms is high, it can be said that it is advantageous to acquire them, especially when observed in the long term.
